What is the role of oxygen in OAC welding?

In Oxy-Acetylene Cutting (OAC) welding, oxygen plays a crucial role as it supports combustion and significantly increases the heat generated in the welding process. When oxygen is combined with acetylene, it enables a more efficient and hotter flame. This higher temperature is essential for melting metals and effectively conducting the welding process.

The combustion process relies on oxygen as a vital reactant that supports the fire generated by the acetylene. Without sufficient oxygen, the flame would not reach the necessary temperature needed for the welding materials to melt and fuse effectively. Therefore, understanding the function of oxygen as a combustion supporter highlights its importance in achieving the desired results in OAC welding.
